Loading member

The invention relates to a substantially L-shaped loading section which, together with the corresponding loading member, can be arranged on the bottom of the crate, each loading member arranged on one of the two parallel lower edges of the crate and kept in close contact with it by means of circumferential straps or a pack of foil, allowing the members to form the legs of the crate.

Background to the profession

The use of the loading members of the upper row in carrying the crate is known, with the loading member arranged together with the corresponding member along the two parallel lower edges of the crate to protect the crate. The loading links are essentially L-shaped, and are held firmly by the wrapping material. There is a larger number of parallel and slightly spaced ribs on one L-piece lane. The L-piece belt with ribs is basically completely covered with ribs. Lifting the crate with a forklift is disturbed because it is difficult to insert the forks of the forklift under the crate without damaging the loading members and their ribs. This is not entirely satisfactory.

BRIEF DESCRIPTION OF THE INVENTION

It is an object of the invention to provide an upper row loading member of relatively simple structure and, when two identical loading members are mounted on two parallel lower edges of the crate, said members allow the forks of the forklift to be inserted under the members (when carrying the crate) without causing them much damage or heavy wear on the loading links.

The loading member according to the invention is characterized by the fact that one L-piece lug has at least two embossed hollow lugs on the surface, intended to be facing the surface carrying the loading lug, with two of the lugs having at least a half spacing the length of the member and a width less than or equal to half the width of said lane and beyond to substantially border the lugs to the edge to which the Lkosa laces extend. The result is that the loading link is very light due to the hollow attachments as well as very durable. When two identical loading members are mounted on the two parallel lower edges of the box and the straps or packing film are wrapped around the box and the members, the loading members are subject to only minor wear when the box is transported with a forklift and said wear is limited to the outermost part of the belt, which has attachments. The loading links also have the advantage of being stacked when not in use.

According to the invention, said belt can be provided with a small embossed nozzle at or near both ends of said belt, and a large embossed nozzle can be provided between the two small nozzles, preferably halfway between them. The loading links are therefore suitable for carrying particularly heavy crates.

According to the invention, the attachments may have the shape of substantially truncated pyramids, thereby achieving excellent rigidity in the walls of the attachments.

According to the invention, the length of the large nozzle in the longitudinal direction of said lane is 13.5 times the length of the small nozzles, thereby obtaining a particularly useful embodiment.

Further, according to the invention, the angle between the cross-sectional lugs can be substantially L-shaped between 82 and 88 °, preferably about 85 °. It follows that the loading members will adhere well to the box when mounted on its said lower edges and when the straps and / or packs are wrapped / wrapped around the box and the loading members.

In addition, according to the invention, the walls of each attachment may be provided with reinforcing ribs around the attachment, so that the position of the straps on each loading member can be relatively maintained.

According to the invention, the width of the second L-piece lane is substantially equal to the width of the first Lkosa lane. This session proved particularly useful.

According to the invention, the loading member may be made of polypropylene (PP), but the outer faces of the attachments are coated with a thermoplastic elastomer (TPE) whose friction coefficient μ is to be at least 0.5 relative to the supporting surface (for example, truck deck) . It follows that, when mounted on a crate, the loading member does not easily allow the crate with the loading members to slide over the loading surface, for example, over the deck of a truck.

According to the invention, the length of the loading member is between 750 and 770 mm, preferably 760 mm, and the height of the attachments may slightly exceed the thickness of the forks of the fork loader and preferably be about 35-40 mm. This allows the bulk of the forks of the fork loader to be inserted under the loading link.

In addition, according to the invention, the length of the small nozzles is less than or equal to half their width. This implementation proved to be particularly useful.

Finally, according to the invention, the width of the large attachment may be less than the width of the small attachments, and the length of the large attachment is greater than the width of the large attachment, preferably 1.7-2.0 times the width. This design proved to be particularly useful.

The best ways to carry out the invention

The loading member 1 with a cross-section of the substantially L-shape shown in FIG. 1, can be arranged together with the corresponding loading member at the bottom of the box 3 (see Fig. 4), with each member arranged on one of two parallel edges 3a and 3b respectively. With the help of the circumferential straps 5 or the foil pack, the loading members are kept in close contact with the box. On the lane 2 facing the load-bearing surface (such as the deck of the truck), the loading member 1 has at least two embossed hollow lugs 7 ', 7, T. Two of the lugs, namely lugs 7' and 7 ', have a spacing a ( see Fig. 3), which is at least half the length 1 of loading Article 1 (see Fig. 2). In FIG. 1 is the actual spacing a of about 0.80 x 1. The width b of each extension T, T, T 'is less than or equal to half the width b2 of lane 2. The terminals 7 ', 7, 7' are adjacent to the edge 4, to which the webs 2 and 6 of the loading member are projected.

As shown in FIG. 1, the embossed lugs 7 'and 7' can be relatively small and can be arranged near opposite ends of lane 2 of the loading member. The nozzle 7, which is a relatively large nozzle, is arranged between two small nozzles. Preferably, the large nozzle is arranged, as shown, halfway between two small nozzles 7 'and 7.

As shown in FIG. 5, each attachment can take the form of a substantially truncated pyramid. The reinforcing ribs lOa, lOb, lOc, may be imprinted on the lateral surfaces of the truncated pyramid (not all reinforcement ribs have reference numbers). These ribs can extend from the attachment or into the attachment.

The large nozzle 7 may have a length x (see Fig. 3) corresponding to 1-3.5 times the length x of the small nozzles 7 ', T. The angle between the lanes 2 and 6 of Article 1 with a cross-section may be substantially L-shaped. 82 and 88 °, preferably about 85 °.

As shown in FIG. 6, guide grooves or projections 8 on the sides thereof are provided at least on the lanes 2 and 6 of the L-piece, intended to be facing away from the crate, said guide grooves or projections allowing for the installation of wrapping strips 5 for loading articles and box 3 or fastening plastic film wrapped around the members and box. The last option is not shown. We can use a stretch film or shrink film.

As shown in FIG. 1, the second lane 6 of the L-piece may have a width b6 that is substantially half the width b2 of the first lane 2 of the L-piece.

The loading link may be made of polypropylene (PP). In addition, it is possible to coat the outer surfaces of the 7 ', 7, 7' nozzles with a layer of 12 thermoplastic elastomer (TPE) to increase the friction between the loading member and the supporting surface (such as the truck deck). Preferably, the elastomer used has a friction coefficient μ of at least 0.5 relative to said support surface.

The length of the loading link can range between 750 and 770 mm, preferably 760 mm. The height h (Fig. 2) of the attachments 7 ', 7, 7' may slightly exceed the fork thickness of the fork loader; it is usually about 35-40 mm high.

As shown in FIG. 3, the length x of the small fittings 7 'and 7' may be less than or equal to half their width b.

The large nozzle 7 shown in Figures 1-3 may have a width b that is slightly smaller than the width b of the small nozzles 7 'and T.

The invention can be modified in a number of ways without departing from the scope of the invention, as can be seen from the attached claims.
